In a recent Dark Reading article, researchers uncovered active exploitation of a zero-day vulnerability in the CentreStack file-sharing platform. This breach puts sensitive enterprise data at risk and exemplifies a troubling pattern: attackers increasingly targeting trusted business software, exploiting unknown flaws that go undetected until it’s too late.
For small and midsize businesses, the implications are clear—traditional cybersecurity methods are no longer enough.
What Happened with CentreStack?
CentreStack, a file-sharing solution used by businesses to manage and sync corporate data, was found to have a critical zero-day vulnerability. This flaw was actively being exploited in the wild, enabling threat actors to gain unauthorized access to user data. What’s especially dangerous is that this was a previously unknown vulnerability—meaning it couldn’t be detected by conventional tools reliant on signatures or known behaviors.
This kind of attack sidesteps antivirus software, endpoint detection and response (EDR) tools, and even many modern threat-hunting systems. The moment attackers weaponize a zero-day, the window of opportunity opens—and detection lags behind.
By the time you're responding, the damage is already done.
Why This Should Alarm Business Owners
The CentreStack incident highlights three critical points for business leaders:
-
You can't detect what you don't know: Zero-days are, by definition, unknown until they’re discovered—usually after being exploited.
-
Detection-based systems are reactive: They rely on after-the-fact alerts. Even the fastest detection still allows an attack to run its course.
-
Modern attacks are faster and stealthier: Threat actors are using automation, AI, and legitimate tools to make attacks harder to detect.
These facts make it clear: the "detect and respond" model is no longer sufficient as a frontline defense.
The Proven Alternative: Isolation and Containment
That’s where AppGuard comes in. Unlike traditional security solutions that attempt to detect threats after they’ve executed, AppGuard prevents them from ever executing in the first place.
Here’s how:
-
Prevents processes from misbehaving, even if they’re compromised or weaponized
-
Stops fileless malware and scripts before they act
-
Blocks zero-day attacks without needing prior knowledge of the threat
-
Protects endpoints without constant updates or cloud lookups
This approach—isolation and containment—puts proactive barriers in place, effectively neutralizing threats before they have a chance to do harm. It's not about chasing the attacker; it's about ensuring they can't move, escalate, or execute in the first place.
AppGuard has been used successfully for over a decade in high-security environments and is now commercially available for businesses of all sizes.
Don’t Wait for the Next Breach
Incidents like the CentreStack zero-day aren’t rare anymore—they’re the new normal. The question isn’t if your business will be targeted; it’s when—and how prepared you are to stop it.
At CHIPS, we help business owners rethink their cybersecurity strategies with AppGuard’s battle-tested protection model. If your current approach relies on detecting and responding to threats after they happen, let’s talk.
Let us show you how to move from reactive to resilient.
